"'It'is' also known to provide a supply ofja' hoseshaped packing material round a filling tube for the goods to befpacked, to pull out a length of the packiiig hose required for producing one packing, to close the fore 1 end of the hoseof' packing mateiial; to fill the desired quantity of goods intothe' 'closed' hose and thenlto'lace the hose toge'ther'behind the goods andto disconnect this fo'rin'ed packing from the supply of packing hose.

Withthse known methods for producing a'bag-shaped packing it was particularly diflicult to sufficiently rapidly lace the hose together where the same is to be closed.

It is one object of this invention to provideinexpensive means for rapidly lacing the'hose "togeth'enwhere required. The method according to this invention is broadly characterized in that'the hose is lace'dtogether by means of clamps produced from tapes immediately.

ing fruits or similar piece goods, because the net may easily be compressed to a thin cord .or string in the places where it is to be laced or clamped together so that relatively small clamps and. consequently. small pressing tools, relatively small pressures for closing the clamps and relatively small dimensions of the device are obtained. The net hose is particularly suitable for the said method in which'a supply of the packing material laid round a filling opening or tube is pulledout in lengths required for each packing.

It was found that the shape 'o-ffthe fillingopening or tube is of particular importance especially when'the said net hose is used as a packing material, in order that the net hose may easily and properly be filled andthat a packing of suitable shape is obtained. Therefore it is alfur-ther object of this inventionto provide a suitable shape of the said filling opening of filling tube. According to this invention at .least the opening ofthe filling tube facing the said closed end .of the hose is of oblong. With this arrangement the or elliptical c'ross'sectionf. hose 'whichis closed at its free endis widely spread out by theweig ht of fruit s or other objects filled into the" same so that following fruits are allowed to' roll into theh'ose' in at least two parallel ranges thereby forming thereby prepared for'the next/filling and of the slide 15,theknife 18-.being" adapted for-..c'oopeta-.-...

2:. a flat andv well shaped packing. If the W611 nown. circul'arfillirig opening or 'fillihg ftub'e is used the hose is pulled lengthwise by'the weight of the first fruits filled iiito the. same aridfall the fruits subsequently filled into; the'hos'ewillbe aligned: in one range so that each pack ing is to be brought into suitable" shape before being closed.

' Oneforrn of the method'according to this'invention is described in the following by] way of example with. eferen t dr w n s. lu tm n i e e mple. 0?. e. device for producing apacking in accordance. with this invention.

tus 'sh'ow'ni in Figs. 4 and 5,

' Fig; 7 is'a top view of the driving coupling of the packing device partially in section and I Figs. 8 to 10 illustrate different stages of the production or" the clamps;

' The'packing device illustrated has a table 1 on which a filling device 3fis supported by means of a carrier 2;

and on which table is fixed an apparatus 4' for produc ing'clamps from tapes and for clamping such clamps round 'thepacking hose where required. The filling de vice shown in axial section in Fig. 3 has a filling tube 5 of elliptical cross section, a protecting tube 6 fixed 'to' lllf l filllllg tube 5 and a tube f elliptical cross section v having a flange 7.vv The tube 8' may be inserted between tubes 5 and 6 from the right in Fig. 3.01 from below in Fig. 1 and is held betwecntubes 5 and 6 by friction. A supply of for instance several hundred meters or yards of a hose-shaped net 9 is slid onto the tube 8, the rear end of this net' hose 9'being'led round the rear end of tube 8 and between tubes 8 and 5' out of-the filling device as shown in Fig. 3. As shown in Fig.- l the filling tube 5 is slightly inclined. The fore end of the net hose 9 has been closed at its free end in a mannerdescribed later on so that the hose 9 forms abag closed-at its fore'end and into which fruits or similar piece goods may be filled through the filling tub-e 5. As already pointed out the elliptical-shape of the filling tube is of particular importance for the obtention of a flat packing 10-inwhich the fruits or other piece goods are arrangedinatleasttwo parallel ranges as shown in Fig. 2;

When the desired'quan-tity of'fruits orv similar piece goods is filledinto the net hose the net is tightly compressed behind the. fruits and the thin cord thereby. formedof the netis introduced into the apparatus '4.in

which the cord is laced together in two places by clamping two clamps produced from tapes round the cord formed from the hose and disconnected between the laced portions thereof.. In this way a bagor sausage-like packing is producedwhich is closedat both ends whereas the free end of .the net hose has again, been closed and packing op-. eration as described.

The apparatus for producing the tape clamps is illus;

trated'in Figs. 4 to 10.: The working mechanism of this apparatus isheld between plates 11 and 12 (Fig. 5). A

slide 15 is guided in slots 13 and 14 of the plates 11 and 12 respectively, theslide '15 having at its fore side arelieved slot 17 constituting a displaceable matrix which. is subdividedin two portions by a recess 16. Arcutting.

knife 18 of hard metal is provided at the upper fore edge t n ed. ama

tion with the lower cutting edge of a cutting head 19. Tapes are fed into the apparatus through the cutting head 19. A control block 21 is fixed on the lower face of the slide 15. The head 23 of a lever pivoted at 24 in the plates 11 and 12 enters into a slit 22 of the slide 15. The lever 25 is connected to a crank rod 26. A pin 28 having an adjustable control screw 29 is slidably held in a bore 27 of the slide 15. The pin 28 is under control of a spring 30 tending to push the pin 28 upwards. The spring 30 is fixed at the rear end of the slide 15 and is displaced with the same. The pin 28 has laterally projecting rollers 31 adapted to run onto wedges 32 fixed on the plates 11 and 12 respectively in order to displace the pin 28 downwards against the pressure of spring 30.

A plate 33 displaceable in the same direction as the slide 15 is provided on top of the slide 15. The plate 33 has a bore 34 into which the control screw 29 of the pin 28 may engage as described later on. By means of a plate 35 the plate 33 is connected with the piston rod 36 of an air brake 37 and with one end of a spring 38 anchored'on the plates 11 and 12. By means of a lug 39 the plate 33 is interconnected with a lever 40 of which the other end is pivotally connected with a lever pivoted on a shaft 41 and with a spring loaded stepping lever 43. The lever 40 has a projection 44 adapted for cooperation with a stepping wheel 45 driven by the stepping lever 43. The stepping wheel 45 is fixed on shaft 41 together with two advancing or feeding rollers 46 and a toothed wheel 47. Toothed wheel '47 gears with a pinion 48 assembled with another advancing or feeding roller 49 which is pressed against the rollers 46 by means of springs. The tapes 20 are thus held between the advancing or feeding rollers 46 and 49 and are advanced by these rollers by a determined amount whenever the stepping wheel 45 is advanced by one'tooth.

The tapes 20 fed into the apparatus are guided each between two rollers 50 and 51 having circumferential ribs and slots engaging each other.

Two stamps 52 adapted to cooperate with the matrix slots 17 of the slide 15 are pivoted by means of a hub 53 on a shaft 54 held between the plates 11 and 12. The stamps 52 may be turned clockwise in Fig. 4 under the pull of a spring 55, this rotating movement being limited by a fixed stop pin 57 against which a nose 56 of the hub 53 will abut on the clockwise rotation of the stamps 52 and hub 53. The hub 53 has a control cam 58 adapted for cooperation with the control block 21 of the slide 15 as described later on. A lever 59 is fixed on the hub 53 and a spring loaded control member 61 is pivoted on this lever by means of a pin 60. The lever 59 and its control member 61 abut against a latch lever 62 when the parts of the apparatus are in the position shown in Fig. 4, the latch lever 62 being pivoted on a shaft having an excentric pivot pin 63. A spring 64 is attached to the latch lever 62 tending to turn this lever clockwise in Fig. 4 until an adjustable screw '65 of the latch lever abuts against the control face 25' of the lever 25.

Two fixed matrices 66 are provided opposite the dissertion of the cord the plate 99 returns into the poplaceable matrices 17 of the slide 15, the actual shape in a slit between the matrices 66. The head of a driving lever 69 pivoted on a shaft 70 and connected to a crank 'rod 71 engages a slit in the'head of the knife 68.

Figs. 6 and 7 of the drawing illustrate the driving mechanism of the clamp producing apparatus. This driving mechanism has a cam disc 73-fixed on a shaft.

'72, the crank rod 26 being connected to this disc'73 by means of an attachment which may be displaced'in a radial slit 74 of the disc 73 and may be fixed in a desired radial position. The. edge of disc 73 has a cam,

4 r 7 surface having an offset 75 and a notch 76. A roller 77 engages the cam surface of the disc 73, the roller 77 being attached to a control lever 79 connected to the rod 71 and loaded at its free end by a strong pulling spring 78.

The one half 80 of a claw coupling and a fly wheel 81 are turnably but not axially di'splaceably mounted on the shaft 72, the fly wheel and the coupling portion 80 being continuously driven by a motor not shown over a belt pulley 82 and toothed wheels 83 and 84 during operation of the packing machine. A second half 85 of the claw coupling is mounted on the shaft ,72 on. which it may axially be displaced but not turned. The coupling part 85 has a flange 86 with-a wedge .87. Two spring loaded pins 88 are inserted in the right hand hearing of the shaft72, pins 88 pressing against the flange 86 of the coupling part 85 thereby tending to shift this part 85 into the position shown (Fig. 7) in which the coupling parts 80 and 85 are engaged. A spn'ng loaded control pin 89 is applied against the cylindrical outer surface of the coupling half 85, the control pin 89 pro-- jecting into the path of the said wedge 87. The control pin 89 is assembled with a plate 90 and the nose of a lever 91 engages the rear edge of plate 90. The lever 91 is articulated on a rocker 92 interconnected with a release key 94 situated on the table 1 by means of a Bowden control cable, the rocker 92 being turned' anticlockwise in Fig. 7 on operation of the release key 94, whereby the lever 91 is pulled downwards (Fig. 7) The lever 91 has a slit against the pull of a spring 95. or guideway 96 by means of which the lever 91 is guided on a fixed pin 97.

The parts of the packing device shown in Figures 6 and 7 are fixed on the underside of the plate of the table 1 below the clamp producing apparatus 4.

Slots 98 are provided in the plates 11 and 12 above the fixed matrices 66. The slot 98 of the plate 12 is covered by a plate 99 displaceably mounted at the out side of plate 12 and held in the position illustrated by a spring (not shown) so that a small opening 100 remains between plate 99 and matrix 66 (Fig. 4).

The illustrated device operates as follows:

In the drawing all the parts of the packing apparatus except the coupling half 85 are shown in their rest or zero position. As already pointed out the net hose is now compressed to a cord or string as thin as possible behind the packing. This string. or cord is inserted between the plate 99 and the upper face of the fixed matrices 66, whereby the plate 99 is slightly pushed back (to the right in Fig. 4) to allow insertion of the cord into the slots 98 of plates 11 and 12. After insition shown in Fig. 4 under spring action and retains the cord formed of the net hose in the opening 100 that i is in the proper position for lacing the cord togethershown in its rest or zero position in Fig. 7 but this part 7 will rotate on from the position shown in the direction of the arrow in Fig. 7 until the control wedge 87 abuts against the control pin 89 whereby the coupling half 85 is shifted to the right in Fig. 7 and disengaged from the coupling half 80. For this disengaged position of the coupling 80, 85 the cam disc 73' comes at rest in' theposition shown in Fig. 6, whereby the control roller 77 catches in the notch 76 of this disc.

On operation of the release key 94 as set out above the rocker 92 is turned anticlockwise thereby shifting the lever 91, the plate 98 and the control pin 89 downwards in Fig. 7 until the control pin 89 releases the control Wedge 87 of the coupling half 85 which latter is engaged with the coupling half 80 under the pressure of the pins 88. Immediately after the release of the control wedge 87 the lever 91 which is slightly turned anticlockwise during its downward motion due to its guiding slit 96' releases the control plate 90 and therewith-the control pin 89 so that the pin 89 again engages the outer cylindrical surface of the control wedge 87 and later on the cylindrical surface of the coupling half 85 but cannot thereby revoke the engagement of the couplin 80, 85. a r

,On engagement of the coupling 80, 85 the cam disc 73 is driven in the direction of the arrow in Fig. 6. The control roller 77 has already passed the full rise of the cam face whereby the knife 68 has been returned overlever 79, rod 71 and lever 69 into the retracted. position shown in Fig. 4. On the other hand the crank rod 26 begins to rotatethe lever 25 anticlockwise so that the slide 15 is shifted to the left in Fig. 4 until the hard metal knife 18 hits the tapes 20 which have already been advanced. The tape pieces projecting downwards from the cutting head 19 are now cut off and Fig. 8 illustrate the relative position of the matrix slots 17 of theslide 15 and of the stamps 52 immediately after cutting .ofthe tapes 20. The tape pieces cut off are already slightly pressed between the matrices 17 and the stamps 52 so that such pieces cannot possibly fall down. The matrices 17 are now further advanced to the left (Fig. 4) whereas the stamps 52 are held in the position shown because the lever 59 or more exactly its spring loaded control member 61' still engages the latch lever 62. This condition persistsuntil the tape pieces are completely pressed into the matrices 17 as shown in Fig. 9. Due to the relievedshape of the slots 17 the so deformed and preshaped clamps will not fall out of the matrices. The mechanism is 'so designed that at this moment the lever 25 has lowered the latch leverv62 to such an extent that the lever 62 releases the control member 61 of the lever 59. Small inaccuracies in the adjustment of the parts are without importance due to the spring suspension of the control member 61. Very close adjustment of the working position of the stamps 52 may be obtained by rotation of the shaft of the latch lever 62. When the control member 61 of the lever 59 is released as set out above the hub 53 and the parts connected to the same are free to turn anticlockwise, this rotation being effected by the control block 21 of the slide 15, which engages the control cam 58 of the hub 53 when the slide 15 further advances whereby the stamps 52 are turned out of the path of the slide 15. e matrices 17 with the tape clamps preshaped as shown in Fig. 9 are further advanced towards the fixed matrices 66 where the longer, lower portion of the preshaped tape pieces is bent until it abuts against the offset 67 of the matrices whereas the upper portion of the preshaped clamp is bent and overlapped over the lower portion thereof. Before engaging the fixed mat rices 66 both ends of the preshaped tape pieces have enclosed the cord formed from the net hose and the tape clamps illustrated in Fig. 9 are now tightly clamped round the net cord thereby lacing the same together in two places.

At the end of the working motions required for producing the tape clamps and clamping the same round the net hose the cam disc 73 has turned to a position in which the control roller 77 reaches the offset 75 so that the lever 79 is turned anticlockwise under the pull of the spring 78, whereby the knife 68 is rapidly advanced to the right in Fig. 4 in order to cut off the cord formed from the net hose between the clamps previously applied to the same.

On further rotation of the cam disc 73 the control roller 77 is lifted again and the knife 68 is retracted. At the same time the slide 15 is returned into the zero position illustrated in Fig. 4 whereby the parts 53 and 62 are returned to their respective zero positions'by springs 55 and ,64 respectively.

At thegend of the working motion of the slide 15 the screw 29 has engaged the bore 34 of the plate 33 whereby the plate 33 has been coupled with, the slide 15 and is moved with the same when the slide 15 is returnedinto its rest position as set out above, that is the plate33 will be moved to the right in Fig. 4 the springs 38 being put under stress. During this returning movement of the slide 15 the rollers 31 of the pin 25 will run onto the wedges 32 thereby pulling the pin 28 and the screw 29 downwards until the screw 29 is retracted from the bore 43 so that the plate 33 is disengaged from the slide 15 and is pulled back into the position illustrated under the pull of springs 38. During the movement of the plate 33 to the right the stepping lever 43 has been set back by one tooth on the stepping wheel 45 so thatthe stepping wheel 45 is advanced by onestep, when-the plate 33 returns into its rest position, whereby the advancing rotation is limited by the projection 44 .of'the lever 40. Thereby the feeding rollers 46 and over gears 47, 48 the feeding roller 49 are turned by a predetermined angle and the tapes 20 are advanced by a predetermined length. The brake 37 provides for a reduction, of the feeding acceleration without which a regular feeding length of the tapes 20 cannot be obtained althoughthe feeding rollers 46 and 49 are roughened for;.instance grooved. Buffers (not shown) may be provided onthe cutting head 19 for taking up the impact of the returning plate33. j

On further rotation of the claw coupling 80, .85 the control wedge 87 again engages the control pin '89, and disengages the coupling so that the cam; disc 73 stops in the position shown in Fig. 6. The packing device has thus returned to its initial position. In the meantime the ends of the net closed by means of the tape clamps are removed from the clamping apparatus 4 and another prepared packing may now be finished as described by another working cycle of the apparatus 4.

In order not to initiate a second or third operating cycle of the apparatus 4 when the release key 94 is continuously. held in its operating position, control of the pin 89, by. the lever 91 is so designed that engagement of the coupling 80, is allowed but once independently of the period during which the release key 94 is depressed. I
